Description

The invention relates to a wind turbine with a latticed or honeycomb construction structure comprising a plurality of wind generator modules.

The use of wind energy represents one of the future technologies in the field of energy production from renewable energy sources, whose development is on the rise.

Wind generators are small wind turbines for generating electrical energy from wind and are due to their smaller size compared to wind farms suitable to be installed in urban areas or buildings.

The DE 10160 836 A1 discloses a wind turbine that is universally and nationwide applicable, regardless of the local conditions, especially in areas with high population density in almost all wind conditions. The wind turbine described has a modular structure and consists of interconnected framed wind generator modules, which can be quickly and easily assembled into a size and shape adapted to the installation site system. A structurally similar, also modular composite wind turbine is in the US 7,592,712 B2 claimed.

From the US 7,595,565 B2 For example, a wind turbine wall designed for do-it-yourself construction and comprising a plurality of wind power generators is known. The known wind turbine wall consists of individual modules in which the wind power generators are rigidly mounted in a socket. The bush has on the outside three evenly distributed on the outer shell radially aligned pins on which are attached to connect several sockets rods.

The DE 920 208 B describes a tubular mast telescopically slidable pipe sections for carrying, inter alia, a small wind turbine.

From the DE 87 01 515 U1 a Eckverbindungselement for inter alia scaffolding is known, which is designed as a plug connection element and which has four rod-shaped projections in the central region of its rod-shaped base body, which protrude radially.

A disadvantage of the known modular wind turbines is that they extend only in a two-dimensional direction (height and width), making an adaptation to the local conditions only within limits is possible Moreover, the wind generators are rigidly connected to the carrier systems, creating a wind-oriented orientation Wind generators is prevented.

The object is therefore to provide a modular wind power plant whose structural properties include more degrees of freedom, so that a spatial modular structure with extensions in the height, depth and width is possible and can be flexibly adapted to the wind conditions and wind directions.

To achieve the object, a scaffold-shaped Windkraftanlagenkonstrukt is specified, which consists of a plurality of wind generator modules, each Windgeneratormodul at least two connecting tubes, at least one corner connector and a support tube on which rotatably and / or rotatably a wind generator with a rotor, a generator and a Wind direction tracking device is set up, has.

Also, mixed constructions of upwardly and downwardly stepped staircase-shaped scaffolding sections can be formed, so that uniform or nonuniform waveforms can be formed from the wind generator modules.

In a further preferred embodiment, the wind power plant construct is designed as a spatial lattice structure, in which horizontal wind generator rows are preferably arranged alternately above and behind one another, wherein each wind generator row is arranged vertically and horizontally offset from the adjacent wind generator rows. Also, mixed constructions of spatial gratings and staircase or step-shaped frameworks can be formed.

To produce a uniform appearance, all connecting tubes preferably have the same length. To produce irregular framework structures, however, connecting pipes of different lengths and corner connecting pieces with a different number of connecting pins for connecting pipes can also be used.

Due to the rotatable and / or rotationally movable mounting of the wind generator on the support tube, each individual wind generator in the wind power plant construct according to the invention can be turned individually into the wind, whereby yield losses due to changing wind directions are minimized.

For the edge-side termination of the wind turbine construct, the support tube of a wind generator module positioned at the edge can be equipped with an elbow at one or both ends, via which the support tube can be connected to a connecting tube. The angle piece is preferably a bent piece of pipe, which is prepared at one end for receiving the support tube and at the opposite end for receiving a connecting tube.

In order to ensure a free rotational and / or rotational mobility of the wind generator around or on the support tube, between the wind generator and the support tube, a sliding or sliding contact or an interface for non-contact transmission of the generated current from the generator to the conductive paths is established.

For attachment between opposing or staggered structures, structural parts or geological formations or for fixing to the ground is at least one wind generator module located at the edge Windgenerator module with at least one means of attachment (anchoring means) on a surface of a building, on a building part or on a geological Formation equipped. Preferably, the anchoring means is an attachable at the free end of a connecting tube tail. Alternatively, corner fittings or elbows may additionally comprise an anchoring means.
